Diamond compound is a mixture of diamond particles and a grease base. Diamond particles are graded for size by filtering through a mesh. Diamond compounds are used in the final finishing phase. Diamond compound is available in grades from 90, very coarse (80 to 100 microns), to 1/10, the finest (0 to ¼ micron). The coarse grades, 90 to 1000, are used for cutting. The finer grades, 200 and up, are for shining. Diamond compound can be used with brass, wood, nylon, and felt laps pushed by a profiler. Diamond compound is also used with brushes and felt buffs driven by a die or pencil grinder. Diamond polishing removes stone and emery scratches and is the final step in producing a “mirror” finish.
